WINDING DEVICE FOR AUTOMATIC MUSICAL-INSTRUMENT MOTORS.

SPECIFICATION forming part of Letters Patent No. 757,095, dated April12, 1904.

Application filed December 21, 1903. Serial No. 186,726. (No model.)

To all whom, it may concern.-

Be it known that we, WILLIAM F. COOPER,

J r., and HERBERT E. SHARPs, citizens of the.

United States, residing at Chicago, county of Cook, and State ofIllinois, have invented new and useful Improvements in Winding Devicesfor Automatic l\IusicalInstrument Motors, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof.

This invention relates to means for winding amechanical motor whosefunction is to operate the controlling devices of an automatic player ormusical instrument by means of the foot-operated devices for supplyingthe instrument With air, either for operating the automatic mechanismwhich contiols the sounding devices or for operating the soundingdevices. It is shown in connection With an automatic piano-player, inwhich the air is supplied for the purpose of operating the automaticplaying mechanism; but. it is not limited to use in this particularsituation.

It consists in the features of construction set out in the claims.

In the drawings, Figure 1 is a plan view of a piano-player having themotor wound by means of our invention, the rollers, trackerrange, andcase being in part broken away to disclose the pedals. Fig. 2 is asectional elevation at the line 2 2 on Fig. 1. Fig. 3 is a detailsection at the line 3 3 on Fig. 1. Fig. 1 is a detail section at theline 1 4 on Fig. 2.

In the drawings, 1 is the foundationboard, so called, upon which, at theforward side, there is mounted the exhaust-bellows 2 or chamber fromwhich the air is exhausted or in which it is maintained in rarefiedcondition by the pumpers 3 3, which are hinged to the rear side of saidfoundation-board. This construction is a common one in musicalinstruments, and we adopt it in this instance for the purpose ofutilizing certain features of it for our present invention. From theupper end of the oscillating side 3 of the right-hand pumper thelever-arm 5 is extended forward, being attached by an angleflange 5,which clasps the upper right-hand corner of said board to obtainfastening on both edges, the arm extending up a little from the angularfastening, so as to overhang and extend forward above the upper edge ofthe foundation-board, because it is desirable to avoid notching thisboard or otherwise in any manner weakening it at this point. Thefoundation-board, it will be understood, extends to the ends 6 6 of thecase for rigid attachment thereto and necessarily is exposed to thestress in both directions of the action of the pumpers 3 andexhaustbellows 2.

Upon the upper edges of the foundationalong the right-hand edge of theoscillating side 3 of the left-hand pumper. The arm 10 is engaged withthe pumper-board 3 by its lower end, which is'thrust into an eye 11,formed at the edge of said board and projecting beyond the bellows?sides for that purpose. The axis of the shaft 8 with this constructionis only a short distance out of line with the hinge of the right-handboard 3, and as the swinging of the right-hand board 3 vibrates thelever-arm 5 up and down at its forward end so the swinging of theleft-hand board 3 by the engagement of the arm 10 with the eye 11 onsaid left-hand board 3 rocks the shaft 8 and vibrates the lever-arm 9 atits'forward end similarly and to substantially equal extent. 7 V

The motor, represented conventionally and in outline only, (indicated bynumeral 12,) is mounted upon the platform-board 13 in a position at oneside prefcrably, as shown, the right-hand side-of the tracker-range 14:and rolls 15 and 16, which carry the controllingsheet. The tracker-rangerolls and control ling-sheet, as well as the motor, are shown onlyconventionally and partially, the only purpose of showing them being toindicate the relative position of said parts with respect to thoseconcerned in the present invention.

The drawings illustrate a motor of the type shown in our Patent No.697,7 5 1, dated April 15, 1902, the details of which it is notnecessary to illustrate or explain in this application further than topoint out that it is wound by means of cables 18 and 19, extending fromwinding-pulleys 20 20 of the motor back and down about suitableguidepulleys 21 21, mounted on the platform-board and guiding saidcables into the rear part of the case behind the forward screen-board22. The cable 18 is connected by a link 28 to the forward.

end of the lever-arm 5 of the right-hand pumper-board 3* and the cable19 by a similar link 23 to the lever-arm 9 of the rock-shaft 8, which isoperatively connected with and actuated by the left-hand pumper-board 3,as described.

hen the motor is wound tight-that is, to the maximum tension for whichthe winding devices are adaptedthe continued action of the pumpers nolonger having any effect on the winding-pulleys the back-and-forth playof the levers 5 and 9 would simply take up and straighten the slack ofthe cables if the ends of the cables were positively attached to thelevers. Preferably for strength the cables are of material not extremelypliable, and the stiffness of the cables, while not so great as tointerfere with their operating properly around the guide-pulleys and thewinding-pulleys when performing the work of winding when they are undertension to the extent of the tension of the springs which are beingwound, is nevertheless such that if the play operated merely to take upand straighten the slack of the cables there would be liability to liftthem out of the grooves of the guide-pulleys or winding-pulleys or ofotherwise displacing them from proper position for winding. To avoid,therefore, such action on the cables, we provide for the play of thelever with respect to the connections by which it operates the cables byextending the links 23 23 from the cables 18 and 19 through eyes 5 and 9in the ends of the levers 5 and 9, respectively, through which the linksplay loosely and freely and furnishing the links beyond the eyes withstopnuts 2 1, which may be adjusted to takeup any slack in the cablesand otherwise to cause the parts to act snugly in winding. We have shownthe oscillatingboards 3 3 of the pumpers provided at their lower endswith the rigidly-attached and forwardly-projecting pedals 25 25 foroperating the pumpers by oscillating action of such rigidly-mountedpedals; but for the purpose of the present invention in one aspect themode of actuating the oscillating boards of the pumpers is notessential, and other connection might be employed from adiiferentlyanounted pedal for that purpose. However, on the other hand,the same action of the winding mechanism might be obtained by a pedalhinged at an elevated point corresponding to the position of the hingeof the oscillating'board 3 of the pumpers, and from this point of viewthe pedal 25 and board 3 may be considered as one element, since theyare, in fact, rigid, and that element be regarded as the pedal,disregarding in this as pect of the invention the function of the board3 as being a part of the pumper. We consider our invention, therefore,broadly, to involve the employment of a pedal hinged at an elevatedpoint and having at such elevated point or near it a lever-arm forconnection with the Winding-cable and as involving also in theconstruction'shown the utilizing of the oscillating board of the pumperfor operating the winding mechanism by means of a lever arm on saidoscillating board, as described.

Specifically, the invention involves the two features above mentioned inone structure in which the pedal, broadly considered, comprises as arigid part necessary for its operation the oscillating pumper-board andthe extension of the lever-ar1n from the oscillating board of the pumper as a specific construction involving extending such lever-arm fromthe pedal. e do not limit ourselves, therefore, to either constructionspecifically nor to the construction in which both features are presentat the same time.
